SQL: `IMPORT DATABASE` misses edge

[gramian]

ArcadeDB Version: ArcadeDB Server v23.7.1-SNAPSHOT (build 2ed2834735647841ad33d9b76408221bfc96055d/1690912950007/main)

OS and JDK Version: Running on Mac OS X 12.6.5 - OpenJDK 64-Bit Server VM 11.0.19 (Homebrew)

Expected behavior

Correct import of graph from CSV files.

Actual behavior

• [ ] Importer skips last edge
• [ ] Repreating the import command causes error Error on importing database / Error on parsing source 'edges.csv (compressed=false size=41)' / Transaction not begun

• [ ] Is the <URL> necessary in IMPORT DATABASE when I have no documents? Should it be optional?

Steps to reproduce

IMPORT DATABASE file://vertices.csv WITH
vertices = vertices.csv, edges = edges.csv, database = test,
typeIdProperty = Id, typeIdType = Long, typeIdPropertyIsUnique = true,
edgeFromField = `From`, edgeToField = To;

and CSV files vertices.csv:

Id,First Name,Last Name
0,Jay,Miner
1,Elon,Musk
2,Steve,Jobs
3,Isaac,Newton
4,Nikola,Tesla
5,Albert,Einstein

and edges.csv:

From,To,Since
0,1,1990
0,2,2005
1,4,1970
