Update Tesla functor cache for 2018 and add tests

TestFileDB entries added in lhcb-datapkg/PRConfig!35 (merged)

changed the description

This is not critical but should go in the next round of releases from 2018-patches, to be used in production, perhaps after the TS.

It can actually go in with the stack that I'm finalising, cf. my email from last Friday.

• [2018-06-19 00:26] Validation started with lhcb-moore-test#92
• [2018-06-19 00:26] Validation started with lhcb-2018-patches#248

merged

FYI, @rmatev, I will cherry-pick this to run2-patches; not to master.
