Change device isolation mode to set errorOnVerifiedUserProblems to …

…`false` (#104)

#92 changed the default mode
for encryption to throw an error when sending a message and the room contains either:
 - a verified user with an unverified device
 - a verifeid user who has changed their identity.

We're not really ready for this (we lack the UI to deal with it), so roll that
back.
