Qute generate missing member cannot generate new template extension when `TemplateExtensions` and `TemplateExtensions0` exist

[datho7561]

Say you have a Qute template that references a property that doesn't exist:

{myObj.asdf}

... and you have two classes in the default package named TemplateExtensions and TemplateExtensions0.

If you apply the code action to generate a new template extensions class, then nothing happens.

I would add that the result is not nothing happens but you end up with a thread looping forever :)
