Simplify isDeviceVerified definitions (#10594)
Browse files Browse the repository at this point in the history 
* Simplify `isDeviceVerified` definitions

Currently, we have two similar but different definitions of `isDeviceVerified`,
and they both do a lot of wrangling that relies on js-sdk internals. We can
simplify it a lot by just calling `MatrixClientPeg.checkDeviceTrust`.

* fix tests

* more test fixes
