[PATCH v3] builtin/remote: quote remote name on error to display empty name

[Shulhan]

When adding new remote name with empty string, git will print the
following error message,

  fatal: '' is not a valid remote name\n

But when removing remote name with empty string as input, git shows the
empty string without quote,

  fatal: No such remote: \n

To make these error messages consistent, quote the name of the remote
that we tried and failed to find.
