After creating a branch, the response for a channel map has that branch repeated several times in the packages.channels key.
How to reproduce the problem:
# starting here:
$ charmcraft status testfacu-charm

# then release:
$ charmcraft release testfacu-charm -r 1 --channel=edge/branch123 --resource=otherstuff:1 --resource=testresource:1
Revision 1 of charm 'testfacu-charm' released to edge/branch123 (attaching resources: 'otherstuff' r1, 'testresource' r1)
# then get the status ("charmcraft status testfacu-charm") which ends up hitting a GET on "/v1/charm/testfacu-charm/releases", and the raw response is:
