Improve of the test output for logical expression with brackets.

[RedBeardCode]

Tries put subexpression into brackets. Checks in the assertion rewriting in one operator is a expression itself and put it in brackets

Fixes #925

[RedBeardCode]

The assertion rewriting tries to combine boolean operations and only show the part which is False. I think this is a nice feature. For example

def test_and_braces():
>       assert (False or False) and False
E       assert ((False or False))
