tests: Fix a scan-build warning about uninitialised variables

Browse Source 
It’s a false positive, but points to a slightly unnecessary use of a
global variable to store something which could be computed per-test.

scan-build thought that arrays of size `n_handlers` could have
uninitialised values accessed in them if `n_handlers` were to change
value part-way through a test (which it didn’t).
