Don't try to dray null initials, actually return null per API contract
when no initials can be found, don't include non-alphanumerics in the
initials. Add test case.
Pass service provider to ctor so we can make the service provider
property immutable. Fill in service label in ctor so it's always set to
something useful. Move creating orphans from Engine to AccountManager
since it exists only to assign an internal id for new accounts, so it
should handled by the account manager anyway.
This allows us to compile the engine tests against the internal VAPI, so
we can unit test internal classes.
* CMakeLists.txt: Add top-level targets test-engine-run and
test-client-run that execute the respective test binaries. Make
the tests target depend on them and make them depend on their
binaries.
* Makefile.in: Add test-client and test-engin targets for convenience.
* src/CMakeLists.txt: Make the right invocation of valac to generate a
correct geary-engine-internal.vapi. Make gsettings schema generation
depend on geary-client so it exists for test-client if the main binary
hasn't been built.
* test/CMakeLists.txt: Split everything up into to builds, one for
test-engine and the other for test-client. Use geary-engine-internal
when building test-engine for access to internal classes and members.
* test/engine/util-idle-manager-test.vala,
test/engine/util-timeout-manager-test.vala: Use Glib MainContext rather
than the GTK main loop for pumping events so the test cases compile
without GTK.
* test/test-engine.vala, test/test-client.vala: New main source file for
test binaries based on old main.vala.
