Probe match reports non-existing hits

[westram]

example using demo.arb:

• match probes with zero mismatches
• matching AGGATACACCTGTTCCCATGCCGAACACAGTAGTTAAGCTTCTTAACGCCGAAAGTAGTTGGTGGGAAACTGCCTGCGAGGATAGGAAGCTGCCGCGC works fine (reporting one hit in LacBulga from which probe has been taken)
• matching AAGGATACACCTGTTCCCATGCCGAACACAGTAGTTAAGCTTCTTAACGCCGAAAGTAGTTGGTGGGAAACTGCCTGCGAGGATAGGAAGCTGCCGCGC (same as above, prefixed by 'A') reports an additional hit in MicLuteu, with
  • mismatch=-75
  • N_min=36 (because it hits the end of the sequence)

• [11158] adds unittest producing wrong mismatch values and two negative mismatch values
