Fix a bug reporting incorrect number of consensus peaks on the terminal

[VJalili]

This PR fixes a bug where MSPC is not reporting a correct number of the identified consensus peaks on the terminal. The issue is related to the recently added stranded analysis (#176), where MSPC wrote in the terminal the number of strands instead of the peak count for consensus peaks.

This PR adds a unit test to reproduce the issue and fixes the bug.

Thanks to @MeriemBahda for reporting this bug!
