fix: Make the logic around last_count working (#106)

Did 2 changes here:

First is the important one where I removed `&& [[ $last_count -ge 0 ]]`
as that was blocking changing last_count, because it was initialized to
-1. Now it should work as expected.

Second I made sure warning is printed if we fail to obtain current count
value.
