Add additional tests for uri module

[benalleng]

This expands the test coverage for the uri module covering all mutants that currently exist.

This will likely become the narrowest scope of my mutant ci coverage so that we can start with full coverage and expand the scope out as we catch more mutants.

Here is the mutants out for payjoin/src/uri/*.rs as of c1cc487

This test doesn't look super useful. If the goal is to add mutation coverage for is_output_substitution_disabled a more useful test would be one that parses the pjos parameter and tests the parsed values, like @Gmin2 started here

[benalleng]

Elected to not include a check for is_output_substitution_disabled() as #546 also has complete coverage for that plus the corrected inverse values. Though I did create a serialization test as you referenced in you last review there (though this will likely need to be updated with the inverse 0 <=> 1 in the future still anyways).

ACK 9e871f6

I think we should wait until #546 gets merged (which should be imminent), then rebase this PR and combine/correct the output substitution tests per #578 (comment).
