bindings: python: tests: ignore purposeful type errors

Some of the unit tests intentionally call methods or assign properties
with invalid values to ensure they fail in an expected way.

Type checkers complain for these instances so inform them via directive
that these lines should be ignore for specific errors.

Additionally, some lines that access properties without assigning the
value look like they perform no action to linters.

To appease the linter, read the value into a throw-away variable.
