Update the updater to expect new names for the updater .jar files

We renamed a couple of components recently (in conjunction with a lot
of restructuring, including a move to the net.imagej.* packages). The
updater was unfortunately left behind, still thinking that the naming
convention is "ij-*.jar" instead of "imagej-*.jar".

Move the writeJarWithDatedFile() method into the UpdaterTestUtils

It is really a helper, not a test case in of itself...

No need to pass the class to createTemporaryDirectory() any longer

SciJava common now lets us use a more convenient method.

Rename some temporary directories in the tests

Now that our tests consistently write into target/ rather than tmp/, we
might as well give the directories conciser names.

UpdaterTestUtils: work around bug in scijava-common 2.20.0

There was a bug in 2.20.0 (which pom-imagej 2.15 references) that has been
fixed in the meantime. It only affected tests, so the bug fix is not
crucial enough to merit a full release cascade.

Let's have a work around just so we can run the tests even with the buggy
TestUtils class.
