Update pytest output in Interacting with Tests

[LiamPattinson]

Resolves #3

Updates the output in the 'Interacting with Tests' lesson to something more likely to occur on a learner's laptop.

Fixes inconsistency in which students are instructed to edit test_calculator.py, but the following text assumed they altered calculator.py.

Adds a couple more useful pytest flags, simplifies key points at the end.

What does this mean?

If you have source files that require output and figures to be generated (e.g. R Markdown), then it is important to make sure the generated figures and output are reproducible.

This output provides a way for you to inspect the output in a diff-friendly manner so that it's easy to see the changes that occur due to new software versions or randomisation.
