Fix native buy flow

[Vere-Grey]

• fixes buyFlow test that was done by this PR so I just make the test more robust.
• new test wrapper testWithRepeat which I used to test stability of my fix. You can replace original it('<tests name> with testWithRepeat(<number of repeats>, <test name>. Commit, push to CI, see results, revert commit. ATM I was not able to think of more cleaner solution. Unfortunately, Detox does not provide any support for this whatsoever
• new method waitToHaveRegex - waits for visibility and then with retry mechanism test either text, label or value based on you parameters.

Do we really need this? I am pretty much convinced that this PR solves the problems with instability in buy and exchange flow.

Hmmm, I was not aware and I noticed your comment way to late :(
So. I am not adding any fixed waits or timeout that will make the test longer. Just more robust so here are two options:

• A, ditch the test improvements and just keep two new support methods
• B, keep it all

What do you say?
