functional tests: Upgrade dependencies selenium and splinter
Fixes an error in testing container where installing dependencies for functional tests wants to uninstall system installed urllib3.
Also minor quotes fixes.
Note that dependencies are upgraded only in new dev environments where geckodriver is not yet installed.
Tests performed, in both stable and testing containers:
- Run all tests, no upgrade related failures found. There were some seemingly unrelated test failures in apps: calibre, ejabberd, deluged, minetest, users, transmission , wordpress, zoph.
