* Switch to secure random strings
Because the js-sdk methods are changing and there's no reason for these
not to use the secure versions. The dedicated upper/lower functions were
*only* used in this one case, so this should do the exact same thing with
the one exported function.
Requires https://github.com/matrix-org/matrix-js-sdk/pull/4621 (merge both together)
* Change remaining instances of randomString
which I somehow entirely missed the first time.
* Fix import order
Any UTs for vector-web layer components or functionality should go here.
This used to contain the UTs for notifications before they got moved to react-sdk.
