This fixes a crash with following error:
```

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
AttributeError: 'NoneType' object has no attribute 'getChildByValueElement'
```
A minimal example and testcase is added.
The extra check for nextChild seems to fix it, however i did not read
the whole codebase, so maybe this creates other issues.

I also changed the comment header to run tests on misra-test-avr8.c
because I thought that was the intention to use it like misra-test.c; if
not, I can revert.
* misra: fix misra-3_1 false positive for URIs in block comments
* added unit test, improved new misra 3.1 based on false positives

* Fix misra 8.7 false positives on single function usage
When there is a single usage of a function, we should first check if the
file it is used in, is the same one it was defined in. When this is not the
case, there is no violatior to be reported.
* Fix misra rule 5.9 false positives for exception
The exception for rule 5.9 described in the guidelines allows for
multiple definitions of internal linkage obejcts when these regard a
static inlined function defined in the same header file.
* Fix neglecting of inline keyword flag upon simplifications
When the inline keyword is being "simplified" and the inline flag is
degated to the next token. However, this information might be lost if the next
token itself is simplified/deleted in a futher pass. Therefore, we must
propagated the flag to all the next named tokens, so we can make sure the
function name token itself is tagged with this property.
* add tests for misra addon rules 8.7 and 5.9
