Try fixing mainshelltest: one more passes now

QUrl is not automatically exposed to DBus so the DBus call would fail.
Changed the parameter to QString instead so that DBus invocation works.

mainshelltest: set QStandardPaths to test mode

Parse command line flags with a single dash as a long option

Unlike KCmdLineArgs QCommandLineParser treats options starting with a
single minus as multiple short options by default.

Previously okular -unique would fail with the following error:
Unknown options: u, n, i, q, u, e.

Also changed mainshelltest to use two dashes in case this behaviour
should change in the future.

mainshelltest failures have been reduced from 15 to 4 by this commit.

Fix docdata saving and added a warning message if it fails

If the ~/.local/okular/docdata directory didn't exist previously
creating the docdata file would fail as there are missing paths.

It seems that KStandardDirs used to create the okular/docdata directory
automatically, with QStandardPaths we have to create it manually.

mainshelltest is down to one failed test now

Fix final test case in mainshelltest

as we call QProcess::terminate the exit code will not be 0
