Fix ProviderTestCase2 broken by ag/519661:

Problem:
1. ProviderTestCase2 passes a null as a ProviderInfo to the ContentProvider
2. mAuthority and mAuthorities will be null during the test
3. ContentProvider.matchesOurAuthorities will throw an NPE.

Fix:
Supply a ProviderInfo with authority.

Example bug:
b/17379295
