[SRU]

[Impact]

Unlike usb-creator-gtk, which has a different codebase, usb-creator-kde
has long been non-functional, getting stuck immediately upon launching.
This means that for Kubuntu, post-18.04 Lubuntu, and any user who
chooses to use usb-creator-kde, it is useless.

There is code to setup a progress dialog for when a USB is being written
to, but it is  in the class initialization, so it displays immediately.
This moves that to the actual install method so it doesn't appear until
the user clicks the button the perform the USB install.

[Test Case]

To reproduce the bug, simply launch usb-creator-kde (Startup Disk
Creator in the menu).

If the bug is present, the installation popup immediately displays,
rendering the program unusable.

If the bug is NOT present, the program should wait for the ISO and
target to be specified and the button to perform the install to be
clicked before the installation popup shows.

It is highly recommended that a USB install is performed as part of the
testing if the bug is not present. See below.

[Regression Potential]

The patch is small, applies cleanly, and does nothing to change logic.
It merely moves logic around. There should be no reason why this should
cause any sort of regression.

The most likely cause of a regression would be the fact that the program
has been unusable for so long, it hasn't seen a lot of use and, as such,
its quality is a bit unknown. I would hope anyone testing would ensure
that the basic function is there.
