Queries with unintentional fragment identifier part in test_volumes_negative module

[Eyal Posener]

The following tests, has the hash tag in one of the queries parameter, which splits the url to a url + fragment identifier part.
Some WSGI backends (such as uwsgi) might cut this part of the url, and pass it in a different environment variable.

The tests are:
1. test_get_invalid_volume_id which results in an HTTP GET on .../volumes/#$%%&^&^
2. test_delete_invalid_volume_id which results in an HTTP DELETE on .../volumes/!@#$%^&*()

The hash tag should be removed from the requested ID.

    Use invalid id with rand string instead of special char

    Many negative tests use invalid id with combination of special char
    like '#$%%&^&^'.
    It has the hash tag which splits the url to a url + fragment identifier part.
    Some WSGI backends (such as uwsgi) might cut this part of the url,
    and pass it in a different environment variable.
