preSN masses are still being logged and written from comenv.f

[katiebreivik]

While working through a bunch of merge conflicts, @xevra and I found that comenv.f is still using some prSN masses, e.g.:

COSMIC/src/cosmic/src/comenv.f

Line 59 in ffb858c

REAL*8 mass_preSN, mHe_preSN, massc_preSN

COSMIC/src/cosmic/src/comenv.f

Line 319 in ffb858c

CALL writetab(jp,tphys,evolve_type,

@TomWagg -- was this intentional? I think we may have totally spaced fixing this up with the other core mass changes?

[xevra]

These were being used as globals (common) previously, but then the globals were removed in favor of an expanded bpp, and the preSN variables were removed in evolv2, assign_remnant, but without setting these in assign_remnant, they appear to be called uninitialized in comenv.

I am working on a fix, and should have it pushed to my branch today (and open a PR). However, the disrupt block at the bottom has me confused. I think that should be menv_bpp(1) and menv_bpp(2), but am not 100% sure.
