bash completion doesn't show "remove" option

Flatpak package contains bash script for bash completion feature. If I say `flatpak in<TAB>`, I will got `info` and `install` options.

Flatpak autocomplete options doesn't work for `remove` option. If I say `flatpak rem<TAB>`, I will got only `remote`, and `remove` will not be suggested.
