Travis test for size-solver compiles Agda but shouldn't

[andreasabel]

The travis test named "Compiler tests, benchmark summary, and other test" takes now a felt eternity. It compiles Agda from scratch:

stack build size-solver "${BUILD_ARGS[@]}"
Agda-2.6.2: unregistering (local file changes: .stack-work/dist/x86_64-linux/Cabal-3.2.0.0/build/autogen/Paths_Agda.hs)
Agda       > configure (lib + exe)

Something is going very wrong here...

A quick fix would be to turn off the CI for size-solver (which is of limited value anyway).
Or maybe someone has a clue why this is suddently happening.
