Allow createPartialMock() to not mock any methods.

[corphi]

Right now, createPartialMock($class, []) does the same thing as createMock($class); it mocks all methods. This is somewhat counter-intuitive and caused by the API of the mock builder, where calling setMethods(null) has the expected effect.

As a first idea, I allowed passing null as a parameter value for consistency. But there is no need for createPartialMock to return a complete one - createMock already does that. [] also expresses the meaning better than null (“exactly these methods”). As a bonus, the method signature doesn’t change.

Test included.

Why would you want to not stub/mock any method?

[corphi]

I use such mock objects in tests for setters and getters; mostly it’s about avoiding a call to the constructor. The code to create such objects is the same as in createPartialMock() – except for the methods mocked. These tests could pass a random untested method name instead (in fact, that’s the way the tests work right now), but that’s a silly workaround and will likely break.

Merged manually, thanks.
