This reverts commit b00e886142.
This fixes reporting of coverage by the few tests that run outside of
vim.
The commit that is being reverted doesn't explain why it was committed,
and the git history suggests it was reverted once and then reintroduced
later again. None of those commits explains the why. I can only guess
that the last time this was committed was an attempt to fix coverage
reporting to outside of docker, which it didn't, and additionally it
made coverage gathering less robust (see previous commit). So this is
yet another fix for the inaccurate coverage reporting.
Or maybe it was because `--cov` without `=taskwiki` an argument reports
coverage for tests instead of taskwiki code? Nevermind, I guess, now it
works well.
Not only can we stop ignoring the errors, this also fixes
TestInfoActionNotTriggeredByEnterOnLink which would otherwise cause vim
to complain about g:vimwiki_wikilocal_vars not being available.
`has('python')` and `has('python3')` work the same in Vim and Neovim, so there's
no need for that extra check. That check is even wrong, since Nvim's `:python`
and friends won't work either as long as the Python provider isn't installed as
well.
