Update compose recipient input search logic

[ioanmo226]

When user searches for contact in compose recipient input, it takes 1-5 seconds for search results to come in our iOS app (this applies to browser extension and android app too).
But in gmail ios/android/web app, it takes less than 0.1 seconds for searching contacts.

Maybe we need to download contacts periodically and save them in realm cache?
This needs to be discussed I think.

Would be good to find out why is it that it takes so long. Is the API call so slow? Are we calling more than once? etc.

[ioanmo226]

it's google contact search api call request time

[ioanmo226]

we only call once

ok. On browser extension, we actually do keep a cache and it should be a lot faster the second time. Is it not? Maybe we don't currently cache all, but only cache items that the user actually used. If that's the case, we could start caching all on browser extension too.

this case i think

but only cache items that the user actually used``
