Synthesis fails when given hint from a module opened as an instance #7964

Description

@rvs314

Apparently, an internal error occurs when attempting to run mimer if FromString is in scope and unqualified definitions are allowed. For example, the error occurs in the following program:

open import Agda.Builtin.FromString

data Obj : Set where obj : Obj

ex : Obj
ex = {! -u !}

Attempting to run agda2-mimer with point in the hole causes the following message:

An internal error has occurred. Please report this as a bug.
Location of the error: __IMPOSSIBLE__, called at src/full/Agda/TypeChecking/Substitute.hs:87:26 in Agda-2.7.0.1-b0fa5c5e408fc4739c1af3c5d9cf6d20b9916cdf89483f2ad6c2902093f2d95c:Agda.TypeChecking.Substitute
