GHCi does no respect -ignore-dot-ghci anymore

[SimonHengel]

Steps to reproduce:

$ echo foobar > .ghci
$ ghci -ignore-dot-ghci

Expected results: GHCi is started without any errors.

Actual result: GHCi reports "Not in scope: `foobar'".

We think this is caused by the "-i" flag consuming this argument.

    Fix ambiguous flag resolution (#7138)
    
    Pick longest flag when more than one matches in findArg.
    
    This fixes an issue where -ignore-dot-ghci wasn't honored, because the
    flag was parsed as "-i gnore-dot-ghci".
