All Robot tests started failing on Linux on CI

With the message:

Parent suite setup failed:
SessionNotCreatedException: Message: Unable to find a matching set of capabilities

Which seems to be connected to selenium/firefox/gecko, see:

@bollwyvl any ideas?

oof. i'll take a look.

Ah. geckodriver 0.27.0 will now no longer accept any-old-firefox... it has to actually point at a real firefox binary. The geckodrivers we test with from conda are wrapper scripts, so that the entire firefox path (large) doesn't go on $PATH.

Will have a patch up presently.
