Sources archive fails to build with a custom name

[gobbob]

Hi there

I'm currently trying to generate a service with a custom name, but it is failing when it gets to creating the archive with the following message:

Error: ENOENT: no such file or directory, lstat '/Users/alcocr52/Projects/podcasts-ingestor/podcasts-ingestor.service'

I'm passing a custom name of podcast-stats-dashboard, so the service created is called podcast-stats-dashboard.service.
I can see that the issue is here:

speculate/lib/generate.js

Line 62 in 82e712f

const archiveWhitelist = getArchiveWhitelist(pkg);

The raw package details are being passed rather than the custom ones generated on line 52.
