fix: skip directory creation when reporting to console

[timothykang]

Closes #24

[aj-dev]

Can someone merge this PR to master?

[maksimr]

@timothykang can you separate one test on three:

something like this:

it 'should not create directory if reporting to console', ->
it 'should create directory if reporting to file with type text`, ->
it 'should create directory if reporting to file with type text-summary`, ->

Thanks!

[timothykang]

Test has been split up into two cases, with and without the file report parameter.

I believe the purpose of the try/catch is to prevent istanbul exceptions of one report/browser from interrupting others, which I believe is wise. It was already in the code prior to my changes (in onRunComplete), and I moved it to preserve the existing code as much as possible and to keep things DRY.
