Description of problem:
Calc doesn't interpret 'quoted field as text' / 'detect special numbers' properly - quotation marks are detected on first run but then not detected on a second run - also, they are not imported properly - quotation marks for text detected in the Text Import tool are not striped in the resulting Calc sheet - see attached images (taking note of the 'detect special numbers' check box and the time sequence of the images)

Version-Release number of selected component (if applicable):
$ rpm -qa libreoffice
libreoffice-4.4.7.2-1.fc22.x86_64

How reproducible:
seems reproducible, restarting libreoffice seems to 're-set' so that quotes are detected - then importing a second time, they're not detected 

Steps to Reproduce:
1. import text file with quotation marks defining text fields
2. see above and attached images
3.

Actual results:
intermittent detection of quotation marks for text fields and failure to reflect them in resulting Calc sheets

Expected results:
consistent interpretation of quotation marks for text fields properly reflected in Calc sheets
