Summary:
Fixed a bug when plugin installation status wouldn't be saved between sessions when plugin uninstalled and then re-installed again. Before the fix, after Flipper restart, such plugin was uninstalled again because its package name was not removed from "uninstalledPlugins" state. This was because plugin id was used by mistake instead of name in few places.
To try avoiding this issue in future I've also renamed "uninstalledPlugins" to "uninstalledPluginNames" to make it more clear than package name should be used there rather than ID. As this field is persisted, I also added migration which moves data to the renamed field.
