Plugin doesn't reassign extension if it has already been associated with text

[yasamprom]

If g4 is already associated with text files and plugin is installed after that it doesn't reassign *.g4 with ANTLR language

Solution: Add [this code](https://github.com/objectionary/eo-intellij-plugin/blob/master/src/main/java/org/eolang/jetbrains/EoPluginController.java#:~:text=final%20FileTypeManager%20fileTypeManager,()%2C%20runnableAssociate) in your PluginController
