Lecture2Go returns different URL formats

[Flova]

The URL format of a known l2g video changes randomly(?) this results in a test fail which results in the ci failing sporadically. These symptoms have been discussed previously in #108 and debugging was added in #111. This debugging shows that the URLs differ in an insignificant(?) matter for the production software, but because the URL isn't matching the given URL exactly the test fails.

The important part is where Prof.+Dr.+Olaf+Asbach obviously does not equal Prof. Dr. Olaf Asbach.
This could be solved using a proper URL library to compare or format these URLs.
Alternatively, the second possible URL could be added to the check.
