update subgraph-channels

[Eliaxie]

• Added Account.isActive flag and Account.openChannelsCount to Subgraph-channels
• Fixed Subgraph-channels compile errors (maybe due to a new TheGraph version)
• deployed subgraph

(created another PR for the rebrand branch at https://github.com/hoprnet/hopr-community/pull/156)

hey @Eliaxie, could you move the projects into project folder and also resolve conflicts?

Added resulting subgraph, keep in mind that as per TheGraph Archive Policy the link could expire
