countProjects() raise 'Empty Response!' error, when no project exist

[lczub]

with v0.6.1, countProjects() does not handle the special case "no project exist" .
Expectation is, that countProjects() returns 0 in this case.

Traceback (most recent call last):

Travis reports a broken build.

Seams that the online tests must be updated, too.

failures reported by travis on a linux build environment running against the TL demo server 1.9.13 (dev 20141226) are not reproducible on a win8.1 environment, running the tox test against a TL 1.9.14 (dev) application

failures are also not reproducibly running the tox tests against a final TL 1.9.13 server.
So problem seams to be related by the TL DEMO 1.9.13 (dev) server.

[lczub]

Commit 5c659c6 marks the getProjects() related online test as may fail.
Travis build passed for them

[lczub]

problematic test project inside TL demo was EA975 - Lab. 6 (ID 131604)

The description includes '\x1c' control chars, which produces the parser error .
After replacing them with '?', the parser error does not occur any more.
So the "may fail" marker can be removed again.
