Steps to Reproduce:
click revision navigation or click right click then select Open Changes then select open changes with previous revision

Here is result which didn't show expect commit compare

It should show the comparison between 25ae247 and 17fa8e5

It might cause by firtst-parent flag

Few days ago, I was encountered There is no previous commit. When I use open changes with previous revision, I have located that It might be cause by old version of git (2.17.2) which return no commits, upgrade my git to 2.29.2, gitlen shows result, but something compare with wrong commits.

Possible solution: add rename: false at getPreviousUri to disable first-parent

I can make a PR for it
