enable --all tests in default run_tests.sh

I fugured errors occur on local machine when using --all switch,
and are not spotted with plain ./run_tests.sh

As a means to figure out the error, as well as for better coverage
I suggest we run with the --all as default

..because swarming might not be available at the user's machine (SQL)
use fast-fail (-x) for run_test.sh as default

for faster Travis builds with failure.
move (problematic) tp10x2 test to unittests as default

move from integration, so this test is run on local machines with ./run_tests.sh

Austin suggested a better place to default the -x option
make failfast default in run_tests.py
