add missing filtering to finished games for #348

[gremlinhunter]

Adds missing filters to Finished Games filtering as noted in the following issue: https://github.com/w3champions/website-backend/issues/348

Unsure as to what refactoring rules there are but some could be applied in MatchesController like the following:

• unecessary fields due to primary constructors
• typos such as "Match" -> "Matche"
