Subject: [PATCH] Android: Stop using getPrimaryClipDescription

The function getPrimaryClipDescription was used to establish if the
clipboard data had text, html and/or uris. Analysing QTBUG-106646 and
tst_qquicktextedit showed inconsistent results, namely the description
hasMimeType failed to find html mimetype on copy&paste.
This patch changes it for searching it by hand instead of using
hasMimeType function.

Task-number: QTBUG-106646
