Experiments done AFTER their tech is researched give full points (#80234)

## About The Pull Request
Doing experisci experiments after their tech is researched gives the
full 100% point amount, up from 66%
## Why It's Good For The Game
This encourages actually doing the tedious helpful experiments (like
upgrading the chem dispensers, cryo cells, SMES, etc.) that give a low
point bonus (1.5K pts, etc.) which helps other players. Also, the
scientist doing experiments has zero control over who is researching,
they might be just about to finish the 10K pts HyperNob gas shells
experiment and a random dude walks in and buys T4 lasers for 15K pts
anyway. So now the experiment is worth 3400 pts less for no reason
