TextEditor: fix autoIndent

e70b99c7da49c27b519f2fcacb4e06974ef1f6ad broke the auto indent for all
indenters because those indenters are all based on the text indenter.

Add a fallback indenter that is used if no other indenter is configured
for a document, and avoid the auto indentation only if that fallback
indenter is used.
