Fix mistake in displayModel.DisplayModelTextInfo.getTextInChunks

[LeonarddeR]

Link to issue number:

None

Summary of the issue:

In the getTextInChunks method on displayModel.DisplayModelTextInfo, a fallback with super is used for reading units other than line. However, the function tries to call _getTextInChunks on the super object, which does not exist.

Description of how this pull request fixes the issue:

Removes the leading underscore from the super(DisplayModelTextInfo,self).getTextInChunks call so that it actually succeeds.

Testing performed:

In Wordpad

import displayModel
next(displayModel.DisplayModelTextInfo(fg,"all").getTextInChunks("readingChunk"))

Known issues with pull request:

Out of interest, how did you find this bug? I.e. what is the practical use case that caused you to notice it?

I was trying to get the display model text word for word, but that failed

next(displayModel.DisplayModelTextInfo(fg,"all").getTextInChunks("word"))
  File "nvda\source\displayModel.py", line 479, in getTextInChunks
    for chunk in super(DisplayModelTextInfo,self)._getTextInChunks(unit):
AttributeError: 'super' object has no attribute '_getTextInChunks'

Merged straight to master as none of our code ever exercises this path, and it is really just a typo fix.
