Add unit tests for backup from standby with block incremental.

Browse Source 
These tests are important for an upcoming bug fix related to differing sizes of a file on a primary vs standby.

The test that demonstrates the bug cannot be included here since it causes a test failure, but this commit introduces the infrastructure and one test to guard against a regression in the bug fix.
