Importer: fix error msg when peptide not in protein for not linkable pos

When a peptide is found not found in any proteins when apply linkable
positions, report the attempted linkable positions used as well.
A 'if/else' was reversed for the added part of the error message.
!!  Only which error message was in error, not the processing of data
that was not in error !!
