• Fixes rel property name in setter of constructor

Hi @slapersonne,

Thanks a lot for reporting this!

I think this issue should instead be fixed in TypeScript declaration file here https://github.com/neo4j/neo4j-javascript-driver/blob/1.6/types/v1/graph-types.d.ts#L66. Otherwise backwards compatibility will break when problem is fixed in JS source. Could you please change this PR to fix TS declaration instead?

@slapersonne changes look good to me and we've received the CLA. Thanks!

Could you please squash all commits in one and use the same git account as connected to your github? Our contributor verification is going a bit crazy because of last two commits. Build is red because of this. Sorry.

@lutovich No problem, that should be correct now.
Do not hesitate to tell me is something else is bad or missing.
