plugin rsync and only one file (selected or hovered) doesn't work

[xfzv]

With:

[[manager.prepend_keymap]]
on = ["R"]
run = "plugin rsync"
desc = "Copy files using rsync"

If I select multiple files and press R: no issue, the prompt is showing up and I can manually type [user]@[remote]:<destination>.

However, if I select only one file or hover a file and press R, the task is stuck at 99% and the following error is displayed in task manager:

Micro plugin failed:
runtime error: [string "rsync"]:33: attempt to concatenate a nil value (local 'remote_target')
stack traceback:
	[string "rsync"]:33: in function <[string "rsync"]:21>

Note that

[[manager.prepend_keymap]]
on = ["R"]
run = "plugin rsync --args='[email protected]'"
desc = "Copy files using rsync to default location"

works just fine even if selecting/hovering a single file.

I'll take a look at this when I get a chance.

I have seen issues with the command failing or expecting input and the task not terminating so there should be some improvements made to handle cases like this
