sat solver: nimble reinstalls dependencies from git repositories each rebuild

[mrgaturus]

nimble reinstalls depenciencies from git repositories links each rebuild making each recompile slower.
this doesn't occur in --solver:legacy only with new --solver:sat
easy reproduce:

# Package
requires "nim >= 2.2.2"
requires "nimPNG" # this will not be reinstalled each rebuild so it's fine
requires "https://github.com/mrgaturus/nogui#head" # this will be reinstalled each rebuild

nimble version (the one shipped with new nim 2.2.2)

nimble v0.16.4 compiled at 2025-02-06 02:02:41
