Uninstall command line parsing fix

Since a shift command occurs later in the loop, the --all option does
not need to to shift arguments. This caused a parsing error in the case
when the --all option is followed by other options.

Also removed quotes around a command line that caused shell to try to
find the entire command line as a single file name.
