[docs] [issue28911] Clarify the behaviour of assert_called_once_with

[Michael Foord]

Michael Foord added the comment:

I like the documentation improvement, thank you.

(The purpose of the method is to combine an assert about the arguments the method was called with and an assertion that it was only called once. To change the semantics would be both undesirable and backwards incompatible.)
