Fix coverage reports

[ethantkoenig]

The previous egrep regex was wrong, so no coverage information from integration tests was included in coverage.all.

Also simplifies the make coverage rule by removing an unnecessary loop.

Make LG-TM work

[ethantkoenig]

@lafriks Why do you comment "Make LG-TM work" on PRs that already have the lgtm/done label?

[lafriks]

@ethantkoenig because when you update branch to latest master github loses status checks, so commenting anything makes LG-TM update status for latest commit that is now merge commit. Otherwise GitHub does not allow to merge it as there are no all needed checks passed

[ethantkoenig]

I see, that makes sense
