Moq and Castle.Core versions need to be upgraded

[pwmckee]

When trying to verify a DbSet method has been called the test is giving a false failure.
I tested using the Moq v4.10 that this project requires.
I then pulled down the code and upgraded the Moq version to 4.14.5 (Or really any version 4.11+) and Castle.Core to (4.4.1) and the test passed as it should.

I'm going to branch and make a PR for this if thats ok
