AIrsenal fails if transfers already made in the gameweek

[jack89roberts]

AIrsenal gives a squad incomplete error at the end of the optimisation if transfers have previously been made that gameweek. The recommended transfers are printed but it fails when trying to decide the lineup, e.g. see below:

I think this may need quite a few changes to fix, e.g. we don't add current gameweek transfers to the database and we'd need to check the number of free transfers available is updated correctly etc.

I believe this could be the problem @ParallaX07 and @Sandipbgn are having in #522 but that may be a separate problem.
