Elm doesn't participate in view provider SingleRootFileViewProvider

See original GitHub issue

Hey,

First, thank you for this plugin !

I just installed it, and after restart I got this error:

Language Language: Elm doesn't participate in view provider SingleRootFileViewProvider{myVirtualFile=file:///var/www/html/src/elm/User/Model.elm, content=VirtualFileContent{size=432}}: [Language: Elm]

Details:

Language Language: Elm doesn't participate in view provider SingleRootFileViewProvider{myVirtualFile=file:///var/www/html/src/elm/User/Model.elm, content=VirtualFileContent{size=432}}: [Language: Elm]
java.lang.AssertionError: Language Language: Elm doesn't participate in view provider SingleRootFileViewProvider{myVirtualFile=file:///var/www/html/src/elm/User/Model.elm, content=VirtualFileContent{size=432}}: [Language: Elm]
