can the function name be changed so that the function is loaded before partitions ?

> The testcase is intended to test REPL LOAD with retry. The test creates a partitioned
table and a function in the source database and loads those to the replica. The first attempt
to load a dump is intended to fail while loading one of the partitions. Based on the order
in which the objects get loaded, if the function is queued after the table, it will not be
available in replica after the load failure. But if it's queued before the table, it will
be available in replica even after the load failure. The test assumes the later case, which
may not be true always.
> Hence fix the testcase to order the objects by a fixed ordering. By setting hive.in.repl.test.files.sorted
to true, the objects are ordered by the directory names. This ordering is available with
minimal changes for testing, hence we use it. With this ordering a function gets loaded before
a table. So changed the test to not expect the function to be available after the failed
load, but be available after the retry.
