fix(test runner): handle nil in no-colors output handler #15679

Browse Source 
Problem:
13748512f6 #15610 The no-colors codepath of the nvim.lua test output
handler does not handle nil, leading to weird symptoms if e.g. a test
has a syntax error:

    test/busted/outputHandlers/nvim.lua:105: attempt to concatenate a nil value

Solution:
Coerce to string in no-colors handler.
