android: Don't reset zoom and position on refresh event
Don't call 'zoomAndRepositionTheDocument' for a REFRESH
event. The only two places sending such an event are in
'LibreOfficeMainActivity#onStart' and in
'FormattingControler#sendInsertGraphic'.
I don't see any need to reset the zoom and position in
any of those two cases. Doing so had the effect that any
manual zoom changes would be lost when e.g. switching
between the LibreOffice Viewer app and another one,
after a "Save As" or when inserting a picture.
In my opinion, it's desirable to keep the view
the user had before doing any of those actions and
just rendering the document anew.
To do so, add an extra bool parameter
'resetZoomAndPosition' to the relevant methods
in 'LOKitThread' that says whether a reset
should take place.
