EssentialsX imported homes overwritten on leave

[arnokeesman]

if players included in the Homes import from EssentialsX were online during import, they're not added to the "active" playerdata but just added to the saved playerdata and written to disk
when they leave their "active" playerdata get stored to disk, overwriting the imported data

guess there's 2 approaches to this:

1. check if the server is empty before running
2. check for active playerdata, and just append to that

probably doesn't have any priority, but now at least we know
