Review request for Plasma.


Repository: plasma-framework


Description
-------

settingsFileChanged is called if the plugin metadata file changes, and
reloads the theme if the version changes.

However, if the metadata file now doesn't exist we need to check before
calling .version() otherwise it will assert.

If it doesn't exist, we want to reload the theme so that it will load
the correct thing.

BUG: 372651
