Don't rely on contacst for one-to-one mentions, and remove cursor

[Fixes: #11670]
[Fixes: #11671]

This commit fixes 2 issues.

One issue was due to removing tribute to talk, which added in the
`contacts` map any user you open a chat with, and some code relied on
this behavior.

The second issue was likely due to a react native upgrade which might
have fixed a bug but caused a different issue, which resulted in the
text disappearing when cursor was set.

I have removed that (it was only used on android) and everything seems
to be working correctly, but not so sure about this one.
