Use TruffleError instead of Error while parsing mutually exclusive options

[sukanyaparashar]

ISSUE

Truffle uses the generic Error type in some situations that provide a stack trace to the users that is unnecessary.
For example: Using mutually exclusive options, --url and --network with truffle console and truffle debug includes a stack trace, which is irrelevant to the users, as Truffle doesn't allow these two options to be specified together. See #5296.

SOLUTION

This PR resolves this issue by using TruffleError instead of the generic Error type while parsing the mutually exclusive options, --url and --network with truffle console and truffle debug.

Thanks Sukanya! Do you know, are there other instances of this in our codebase, or is this it?

Hey @haltman-at, I will check the codebase once more if there happens to be other cases where we can use TruffleError instead of Error.

Well if you checked once, I don't know if you need to check a second time! I was just making sure you remembered to check in the first place. :)
