Different mime types are widely used on mobile devices. For example all
text copied from gmail is copied as text/html type.
After 2937cf91c7 commit there is a
regression that makes it impossible to paste any text different than
"text/plain".
To fix it, any "text/*" mime type should be treat as it contains a text
(not only "text/plain"). That will allow to paste different text mime
types.
During this work also tst_qclipboard testset was turned on for Android
and new test (getTextFromHTMLMimeType) was added.
