cli/bash-completion: escape spaces in profile names (rh #1041901) (bgo #709426)

Browse source 
We need to escape spaces and quotes in connection names, so that a connection
name containing spaces (quotes) is regarded as a single argument by bash.
See e.g. http://stackoverflow.com/questions/1146098/properly-handling-spaces-and-quotes-in-bash-completion
