Exclude tests for disabled models in compile stats

[NiallRees]

Fix #1804

Checks if the node is a test, and then if it is enabled.

All models enabled:

(env) [niallwoodward:~/dev/data-dbt]$ dbt compile                                      
Running with dbt=0.15.0-rc2
Found 328 models, 725 tests, 2 snapshots, 1 analyse, 378 macros, 3 operations, 5 seed files, 104 sources

One model disabled before fix (with two tests dependent on the disabled model):

(env) [niallwoodward:~/dev/data-dbt]$ dbt compile                                      
Running with dbt=0.14.1
Found 327 models, 735 tests, 2 snapshots, 1 analyse, 374 macros, 3 operations, 5 seed files, 104 sources

One model disabled after fix (with two tests dependent on the disabled model):

(env) [niallwoodward:~/dev/data-dbt]$ dbt compile                                      
Running with dbt=0.15.0-rc2
Found 327 models, 723 tests, 2 snapshots, 1 analyse, 378 macros, 3 operations, 5 seed files, 104 sources

looks like the flake8 styleguide checker we use isn't happy about this line:

core/dbt/compilation.py:70:31: E701 multiple statements on one line (colon)

Can you just split this out onto two lines?

[NiallRees]

Sure - thanks

It looks like the CI failed for an unrelated reason to the pr, are you able to rerun @drewbanin?
