CATROID-1388 Added CLT for Repeat Until Brick

[moemgva2910]

Wrote a Catrobat Language Test for 'Repeat Until' brick.
https://jira.catrob.at/browse/CATROID-1388

Added CLT since there are currently no tests for this control brick.

Brick Functionality tested:

• Increment var counter until condition fulfilled.
• Decrement var counter until condition fulfilled.
• No increment when condition immediately fulfilled when starting the loop.
• Increment variables within nested loops where the condition of the outer loop depends on the condition of the inner loop.

Looks good, except that the test takes quite some time because of the added delays. Although the way you implemented it, makes it more understandable while the test runs, these tests are mostly used for automatic checking. So I would argue the display of the counters is not necessary. To make up for this you could seperate the test into multiple sprites if possible. That way the test becomes easier to read.

Thanks!
