Fix/startup jvm error after installation update via msi (#1229)

* Remove existing installations with msi installer

* Remove unused x86 wxs file

* Uninstall old msi versions with different upgrade code

* Progress but error 2721 happens on install

* Remove added uninstall previous version wxs stuff

* Use revision as patch number

MSI only uninstalls previous versions in case the version number changed (it only checks the first three numbers (major, minor, patch)).
Thus, to prevent each preview install to result in it getting registered as a new "app" and for it to uninstall the old versions, we have to change the version on each release.

* Deprecate "BuildConfig.REVISION"

* Remove outdated env vars
