Generated `cobertura.xml` has empty `filename` field

[MPThLee]

Describe the bug: I got some bug about codecov stuck on Processing.... I just contact to them and received this response: the cobertura.xml file that you are uploading has a file without a filename. (See this) I'm using github action for testing coverage. GHA log is here: https://github.com/MPThLee/binary-reader.rs/runs/3983116585?check_suite_focus=true Note that I'm using xd009642/tarpaulin:develop-nightly with --security-opt seccomp=unconfined

To Reproduce Please checkout my repository that testing now. https://github.com/MPThLee/binary-reader.rs

Expected behavior Should have proper filename. I think.

This is really interesting, just running it normally (with debug output) gives:

So it definitely thinks there's an unnamed file, either in the DWARF tables and I have failed to handle that edge case... Or somewhere else. I'll have a look deeper to find it, but this is definitely a unique (and maybe fun) issue :thinking:

EDIT: It's because of the .rs in the project name, I'll find where the missing is_file() check should be then make a PR, test to prevent regression and maybe drop a new release later today

Once this CI passes I'll merge the PR and then at some point the new docker images will build and push for you

lmao, it caused by directory name. Anyways, Thanks for fix this issue!
