Building unittests fails

[simonsouth]

This morning jam -q -j2 unittests fails with

src/tests/servers/launch/UtilityTest.cpp: In static member function 'static void UtilityTest::AddTests(BTestSuite&)':
src/tests/servers/launch/UtilityTest.cpp:53:38: error: 'TestEmpty' is not a member of 'UtilityTest'
   "UtilityTest::TestTranslatePath", &UtilityTest::TestEmpty));

This looks like a copy-and-paste error in ​d9bb9513c5e9b36cd4761fffb6f59e141c8aa692; the line ought to read

   "UtilityTest::TestTranslatePath", &UtilityTest::TestTranslatePath));

Continuing, the build fails again with

/(...)/generated/objects/haiku/x86_64/release/tests/servers/launch/Conditions.o: In function `NetworkAvailableCondition::Test(ConditionContext&) const':
Conditions.cpp:(.text+0x488): undefined reference to `NetworkWatcher::NetworkAvailable(bool)'
collect2: error: ld returned 1 exit status

Here the Jamfile changes in ​5f2abaf7df37f5e2e6cab5dffeed209e89759e07 need to be applied to the unit tests as well.

With these two changes the build completes for me. I'm attaching a patch with the fixes.
