Update scope by bidirectional modifier (Semantic bug)

[Martijn-Sturm]

There is a bug in the following file: #https://github.com/chapmanbe/pyConTextNLP/blob/master/pyConTextNLP/tagObject.py
In the limitScope() function

In short: if self has rule 'bidirectional' and is downstream in the sentence compared to object, the scope of self won't be adjusted as it should be.

This should be done by the code from lines 98-101. However, this code is not executed since the if statement preceding (lines 94-97) is executed.
