Mismatched variable names in test_prefix.wdl unit test

[stxue1]

The test_prefix.wdl unit test has a workflow output env_prefixed:

wdl/SPEC.md

Line 8093 in 9c0b9cf

Array[String] env_prefixed = prefix("-e ", env1)

But the expected output is env1_prefixed:

wdl/SPEC.md

Line 8110 in 9c0b9cf

"test_prefix.env1_prefixed": ["-e key1=value1", "-e key2=value2", "-e key3=value3"],

A similar issue is in the serialize_array_delim_task.wdl test. heads is the output in the workflow:

wdl/SPEC.md

Line 9844 in 9c0b9cf

Array[String] heads = read_lines(stdout())

And the expected output is strings:

wdl/SPEC.md

Line 9867 in 9c0b9cf
