ui test for mixing local contacts into results in compose recipients input

[tomholub]

This will later need a ui test, something like:

1. search a string in compose, see results
2. manually add two public keys in contacts - one matching, one not
3. search a string again in compose view, the results should newly contain the matching added public key on top

@tomholub could you provide more details of what needs to be tested here or maybe record video if possible?

Sorry, it's blocked on #298, therefore not actionable.
