S3 methods in local environment are not identified

[mschubert]

Describe the bug

Originally mentioned in #2, identification of local S3 methods is mentioned to be fixed in 7847dd5 (2018).

#47 seems to be for S3 methods in packages specifically.

Related: mschubert/clustermq#256

Reproduce example

f = function(i) UseMethod('f')
f.numeric = function(i) sqrt(i)
globals::globalsOf({ f(1) }, locals=TRUE, recursive=TRUE) # addS3 is no longer documented
# list()

The originally included test also seems to fail now, although it is no longer available. I also no longer see any mention on S3 in the tests or any changes to S3 behavior in the NEWS.

Expected behavior

Shouldn't this identify f.numeric?
