ModuleLicenseProviderTest converted to JUnit
The superclass ContentProvider's "getContext" method is final and cannot be mocked, so a helper method visible for testing was added to allow for context injection. Bug: 175389659 Test: atest -c ModuleLicenseProviderTest Change-Id: I9e20171340ae0a48d74fae44c7b356ea67dba43b
