Change single quotes to double quotes

[melkadze]

Single quotes in the --nsFrom and --nsTo parameters are NOT understood through the command line mongorestore tool, and prevent it from working as intended (instead of replacing test., it replaces 'test.') . Double quotes maintain the consistency of the similarly double-quoted command arguments, and allow this command to function normally.
