[BUG] - Inconsistent line coverage errors.

[JosiahBull]

Describe the bug
I've been seeing inconsistent coverage.

Note that this error is positional for some reason. Swapping the impl for CommError with Auth means the error appears on Auth instead.

Tagging #351 , though it may be user error at this point so don't want to add to that thread right away.

To Reproduce

git clone https://github.com/riptide-org/ws-com-framework/
cd ws-com-framework
cargo tarpaulin --out lov --all #version 0.20.1

Expected behavior
I expected the line coverage to be consistent for the TryFrom implementation.

If you were using llvm coverage this should be improved in the latest release. If you're using ptrace it's potentially unavoidable - there's a bunch of concurrency nightmares with tracing multi-threaded applications which make consistency maybe impossible. Things like --test-threads 1 is an answer.

Sorry for not getting back sooner, I'll keep this issue open if you want to check back in. But otherwise I'll likely close in a month or so
