Filter Clinical Attribute Charts when priority is -1

[haynescd]

Fix cBioPortal/cbioportal#10133

Update chartMetaSet getter to ignore clinical Attribute charts when priority is < 0

• Add LocalDB test (Attributes with priority of -1)
• Test Priority of Session Service and how changes will react to saved charts

@inodb @haynescd I checked the public database and GENIE database, and we currently don't have any attributes that have a value of priority less than 0. So it should be fine to use -1 to remove the attribute.

LGTM, it's very straightforward. Just one more question regarding the clinical tab in the study view, are we also gonna hide those attributes from those columns too?

Ok, awesome. I am going to make a localdb update to add attributes with priority of -1 so I can test this feature.

@dippindots Are you talking about the clinical tab under "Add Chart" Button?

@haynescd For example, in this study: https://www.cbioportal.org/study/clinicalData?id=msk_impact_2017
Just wanted to know if we will also hide priority=-1 attributes in this table
