extend_line_above ignores count

[dead10ck]

It looks like when extend_line_above is selecting the new line range, it takes the count into account for extending below, but above just hardcodes subtracting 1.

I fixed it in the #3046 : https://github.com/helix-editor/helix/pull/3046/files , if need, I separated this part to another PR.
