Fiji --dry-run option will still run the updater and remove files

[carandraug]

Running the launcher with the --dry-run option should make no changes, however, I found that pending update stuff will still run.

As a side note, running the launcher with the --debug option does not show those files being removed (I'm guessing that the handling of the --debug option happens later).

@carandraug Thanks for the report. About --debug: it is picked up as early as possible. So I'm not sure why files being removed aren't reported in debug mode. Maybe just because there aren't debug-level log statements around it at all? I'll check while digging.

@hinerm Remember discussing this recently? Looks like the always-install-updates behavior is already causing consternation. I'll look into how to fix it.
