KPI_2: good title total score multiples by number of identification sections

[amilan17]

Summary and Purpose
The total score for a the title category should be 8, but some records have more than 1 title and the total score multiples by the number of identification sections. This is most common in metadata records that are probably auto generated in THREDDS from NetCDF and have SV_ServiceIdentification sections as well as MD_DataIdentification. It seems that all records with this result are from EBAS.

1. Do we want to check titles for services as well as data?
2. Does it matter if the total score multiplies? Maximum total score should be 8, in the ebas records, it's 24...

Proposal
Change the Xpath from:
//gmd:identificationInfo//gmd:citation/gmd:CI_Citation/gmd:title/gco:CharacterString
to
/gmd:MD_Metadata/gmd:identificationInfo/gmd:MD_DataIdentification/gmd:citation/gmd:CI_Citation/gmd:title

This also occurs with abstracts when there are multiple identification sections (KPI 3)

and all KPIs that assess Xpaths under identification sections: KPI 4 and 6 (temporal  and keywords)....

I confirm that for example this EBAS record ends with total score 24 in KPI 2:
pywcmp kpi validate -k 2 -f tests/data/ebas_FR0013R.20130103120000.20150618000000.steel_canister..air.1y.84h.FR07L_MD-GC_NMHC_offline_FR13.FR07L_NMHC_analysis.lev2.nc.xml
