Manifest usage log error should be non-fatal

[fonsp]

I got this error today in a production server, which caused the process to crash.

Should this error be fatal? I feel like it suddenly surfaces an implementation detail of Pkg.jl, and it should not be a user error.

Perhaps this can be solved automatically, with a warning?
