fix version init

[luccabb]

Description

debug.ReadBuildInfo()

returns an error for some environments, which then panics on info.Main.Version:

panic: runtime error: invalid memory address or nil pointer dereference

this fixes the issue by only updating the version if debug.ReadBuildInfo() succeeds
