Fix sample reports retrieval

[ramonski]

Description of the issue/feature this PR addresses

Please merge #2279 first

This PR introduces the following new getters for samples:

• getRawReports: Lookup sample reports from the report catalog
• getReports: Returns sample report objects
• getReportUIDs: Returns a list of sample report UIDs

Current behavior before PR

Sample reports were assumed to live inside the sample and were retrieved via objectValues

Desired behavior after PR is merged

Sample reports may live in other samples and contain only the current sample in a multi report. Therefore, a catalog search is required.

I confirm I have tested this PR thoroughly and coded it according to PEP8
and Plone's Python styleguide standards.

I suggest renaming getRawReports to be compliant with AT behavior that we adopted for all types (DX included)

[xispa]

We usually use the getRaw* function to return UIDs. I suggest to add the full_objects=False in getReports (along with **kwargs) instead.

Also note that getRawReports could rely on get_backreferences:

def getRawReports(self):
    return get_backreferences(self, "ARReportAnalysisRequest")

def getReportUIDs(self):
    return self.getRawReports()

Also note there is a typo with inlcude_provisional (should be include_provisional)

def getReports(self, include_provisional=True, full_objects=False, **kw):
    ...

[ramonski]

Yes, I thought about this. Shall I rely better on the backreferences instead?

I think that relying on backreferences is better, yes
