"'S.call' seems to originate from 'OpamCudfSolverSig' whose MLI file could not be found"

[kit-ty-kate]

Reproduction case using merlin.4.8-414:

1. git clone https://github.com/ocaml/opam && make -C opam cold

2. Open src/solver/opamSolverConfig.ml at this line: https://github.com/ocaml/opam/blob/0a174e1f8ebcfb9fc885c1ab823eca4b38c0d56c/src/solver/opamSolverConfig.ml#L256

3. Call locate on call

The locate will fail with the error message in the title.

Side note: I have (setq merlin-locate-preference 'mli) in my emacs config.

Regression of https://github.com/ocaml/merlin/issues/1519
