Add Selenium test case for rerunning analysis feature in GobView

[sxprz]

This is part of a Bachelor's Thesis, see this pull request
Since a new feature has been implemented in the above mentioned PR, it would be useful to extend the Selenium test file for GobView accordingly.

The Selenium test flow is the following:

1. It clicks on the "Parameters" tab in the Navbar (center, bottom)
2. It deletes the input string from the input bar
3. The test checks whether it receieved feedback about the invalid input
4. Now, it enters "--incremental.force-reanalyze.funs ["main"]" as parameter into the input bar
5. Enter is pressed
6. Analysis has to be awaited
7. 10 seconds later, the analysis should have succeeded, thus checking if the parameter occurs in the parameter history
8. It is also checking its status afterwards, whether it succeeded or not

DO NOT MERGE THIS PR UNTIL THE ABOVE MENTIONED ONE HAS BEEN MERGED INTO GOBVIEW.
