Fix NC 33.0.0 compatibility, deprecated execute() method was removed

[michael-dev]

NC 33.0.0 removed the OC\DB\QueryBuilder\QueryBuilder::execute() method that was long deprecated.

So this pull request fixes the resulting
Call to undefined method OC\\DB\\QueryBuilder\\QueryBuilder::execute()
errors and restores compatibility with NC 33.0.0

works for me, thx for the patch..

sooner this gets merged into a release the better. this is an essential plugin for those of us who use it, and a NC upgrade showstopper when this plugin is broken.

Hey guys! My nextcloud is currently broken because of this issue. Is there any timeline, when this will make it into a release? Is there anything I can contribute to make the process faster?

Applied patch manually, thanks.
Works with NC-33.0.0 here.

This patch seems to be trivial enough and there are several success reports. Does this also fix the IMAP login method mentioned in #266? What else needs to be done to get it approved and a new version to be released?
I am willing to help since my Nextcloud instance cannot be upgraded as well due to this incompatibility.
Thanks!
