correct online utest uploadTestCaseAttachment

online utests *test_uploadTestCaseAttachment_unknownID* failed with
default Travis config against TL demo project.

reason was, that this tests expects, that no *nodes_hierarchy* entry
with id 4712 exist, but the TL demo project has this.
-> so this test creates unwanted attachment upload into the TL demo
project

To avoid this following is changed:
- uploadTestCaseAttachment_unknownID uses now the ID '0000'
- tox.ini and .travis.yml suggest to use TL demo project with special
use *pyTLapi* instead *admin*
