Fix ambiguous overload in unit test (#4582)

Fixes nightlies. The compiler version used for our nightlies (GCC 5.4.0)
complains about mkFunctionSort({bSort}, bSort) being ambiguous because
we have two variants of mkFunctionSort(): one that takes a single
Sort and one that takes a vector of Sorts. This commit makes the
function call unambiguous by removing the use of list initializations.
