* update deltachat-core-rust to 'ref: More logging for ongoing and get_backup (#4289)' of branch 'stable-1.112'
* update changelog for 1.36.2
* bump version to 1.36.2
* add some feedback at end of upload-release script, similar to upload-beta
* make sure, only one error alert is shown
DcBackupProvider.unref() will soon also emit errors,
see https://github.com/deltachat/deltachat-core-rust/pull/4242 ,
but also before, this was only correct by coincidence
* do not handle events on shutdown
DcBackupProvider.unref() may emit events,
but that may happen also for other reasons.
be explicit by a flag,
relying on activity.isFinishing() or by the already removed observer seems
error prone, esp. on future changes. do not make me think :)
* update changelog for 1.36, core part
* update changelog for 1.36, android part
* bump version to 1.36
* add device message for 1.36
* qualify 'Add Second Device' as experimental also in device message
* apply recent suggestions to CHANGELOG
we already had a confirmation dialog for probably most security-aware users
always when the device is protected by a screen lock.
this commits adds a more on-point text -
and shows the same text in a simple alert in case a device has no screen lock.
while both devices show a progess bar,
the exact percentage is shown on receiver side only.
beside the receiver progress being more accurate,
main reason is not not confuse users by the devices showing
slightly different percentages.
more detailed text about internals,
that maybe even flashes up only for a fraction of a second
is not helpful after first user tests,
and may even scare ppl.
we're also checking for null at some other critical code positions,
so this seems reasonable also here.
this might fix a recently reported crash,
maybe caused by a race condition.
