appveyor should print boost test_suite log on failure

[maflcko]

See

bitcoin/.appveyor.yml

Line 63 in a6c8aed

- cmd: src\test_bitcoin.exe -k stdout -e stdout 2> NUL

However, it should use the -l test_suite log level and show the whole output on failure, similar to

bitcoin/src/Makefile.test.include

Line 371 in a6c8aed

$(AM_V_at)$(TEST_BINARY) -l test_suite -t "`cat $< | grep -E "(BOOST_FIXTURE_TEST_SUITE\\(|BOOST_AUTO_TEST_SUITE\\()" | cut -d '(' -f 2 | cut -d ',' -f 1 | cut -d ')' -f 1`" > $<.log 2>&1 || (cat $<.log && false)

Hi @MarcoFalke , I am quite new to this project and I wanted to help out. Should I add in the -l test_suite argument to the appveyor YAML file? Is there anything from the example mentioned in Makefile.test.include that I need to include after the -l argument, i.e. -t "`cat $< | grep -E "(BOOST_FIXTURE_TEST_SUITE\\(|BOOST_AUTO_TEST_SUITE\\()" | cut -d '(' -f 2 | cut -d ',' -f 1 | cut -d ')' -f 1`" > $<.log 2>&1 || (cat $<.log && false) ?

I think you'd have to write -l test_suite > some_log_name.foo || (cat some_log_name.foo && false) in powershell or whatever language the appveyor thing is using
