MacroBase SQL tests fail because of spaces in path

[AlexP11223]

Some tests that use files fail if path to the project contains spaces:

Tests run: 21, Failures: 0, Errors: 21, Skipped: 0, Time elapsed: 3.905 sec <<< FAILURE!
query1(edu.stanford.futuredata.macrobase.sql.MacroBaseSQLTest)  Time elapsed: 2.324 sec  <<< ERROR!

Something like this seems to work:
