Remove NotImplementedError pass on the out unit tests for the algorithm class

[MargaretDuff]

Description

Instead of allowing tests to pass with a not implemented error e.g.

CIL/Wrappers/Python/test/test_out_in_place.py

Line 164 in b3d8ffe

except (InPlaceError, NotImplementedError):

except (InPlaceError, NotImplementedError):

Line 132 in b3d8ffe

except NotImplementedError:

We should add to the list of functions to test, which tests we want to run e.g. instead of (function, geometry) we should have (function, geometry, bool, bool, bool) with the three booleans corresponding to test proximal_conjugate, test_proximal and test_gradient True/False:

The danger of the NotImplementedError was highlighted by #1854.

Similarly, for the operator tests and
