Remove abbreviations after expandall, compressall

[emdupre]

In returned text after expandall and compressall the original abbreviations are currently kept. For example, after compressall the example string:

'This is a Test String (TS). I hope it is Informative (inf). '

becomes

'This is a TS (TS). I hope it is inf (inf). '

Instead, it might be better to return

'This is a TS. I hope it is inf. '

such that abbreviations are not overrepresented in the text.
