Parser: fix pattern range for idents with trivia

[auduchinok]

Fixes wrong ranges for patterns that contain identifiers with trivia.

Here the parens are not considered a part of the pattern, which results in a wrong pattern range:

let (|A|) = ()

Here the error expression from the recovery rule is placed between | and ) instead of after ):

let (|A|)
