run-tests: partial matching does not work for run_django_tests

[Evan]

It's currently not possible to run just the ppa-assigner or ticket_system tests using ./run-tests. This is because it doesn't go through the same globbing/filtering routine as the other tests.

AFAICS it does go to the same filtering:

$ ./run-tests ppa_assigner --list

ppa_assigner.tests.TestApi.testCopy
ppa_assigner.tests.TestApi.testCopyBadParams
ppa_assigner.tests.TestApi.testFreeNumeric
ppa_assigner.tests.TestApi.testFreeString
ppa_assigner.tests.TestApi.testGetAll
ppa_assigner.tests.TestApi.testGetQuery
ppa_assigner.tests.TestApi.testJSONP
ppa_assigner.tests.TestApi.testPopulateFail
ppa_assigner.tests.TestApi.testPopulateMerge
ppa_assigner.tests.TestApi.testReserve
ppa_assigner.tests.TestApi.testReserveNoFree
ppa_assigner.tests.TestApi.testStatus
ppa_assigner.tests.TestCleaner.testCleaning
ppa_assigner.tests.TestCleaner.testCleaningFailure
ppa_assigner.tests.TestCleaner.testDirtyToClean
ppa_assigner.tests.TestCleaner.testDirtyToCleanFailure
ppa_assigner.tests.TestConcurrency.testReserveConcurrency
ppa_assigner.tests.TestModel.testReserveNoFree
ppa_assigner.tests.TestModel.testReserveTimestamp
ppa_assigner.tests.TestPep8.test_pep8_conformance
ppa_assigner.tests.TestPyflakes.test_pyflakes_conformance

When in doubt about which regexp to use to filter, try:

$ ./run-tests --list

the ticket system test IDs starts with 'ticket' and 'project'

Again, it would be very helpful if I could run all tests for a specific
component just by using the component name. tstrun isn't a logical 'guess'
for the test runner. I shouldn't have to list the tests to figure out how
to run the tests for a component.

> run all tests for a specific component just by using the component name

The test runner only cares about the test IDs which are under user control: the python name space is what matters.

Now, an alternative that has been used in bzr is to define aliases so you could say './run-tests test-runner' and have 'test-runner' translated to '^tstrun' internally, but that's not what this bug is about.

[Vincent Ladeuil (vila)]

The plan is to prefix the test ids with the component directory.
