[PATCH] test: sort the output of the "prefix" test in T610-message-property as needed

[Olivier Taïbi]

the "prefix" test in T610-message-property extracts values from a
(key,value) map where multiple entries can have the same key, and the
entries are sorted by key, but not by value.  The test incorrectly
assumes that the values will be sorted as well, so correct this by
splitting the output using head and tail and sorting each chunk using
sort.
NB: the relevant key/values are as follows.
testkey1: alice, testvalue1, testvalue2, bob
testkey3: alice3, bob3, testvalue3
