create_test_db doesn't respect caching parameters for db backend

[muhuk@…]

line 318 in django.db.backends.creation.py (create_test_db) just takes everything after 'db://' as the cache table name.

        if settings.CACHE_BACKEND.startswith('db://'):
            cache_name = settings.CACHE_BACKEND[len('db://'):]
            call_command('createcachetable', cache_name)

This results a table name of cache?timeout=15&max_entries=100 if CACHE_BACKEND is 'db://cache?timeout=15&max_entries=100'

[Malcolm Tredinnick]

(In [9936]) Changed the way cache specifiers are parsed.

Allows us to reuse the same code in multiple places, avoiding new and
interesting bugs (the testing framework had a DIY version that was slightly
wrong, for example). Fixed #9833.

Backport of r9936 from trunk.
