map_kind directive is not applied on empty rules

6.0.0

Does this issue reproduce with the latest releases of all the above?

What did you do?

We use map_kind directive to replace go_binary and go_library kind rules (with different names).
When all Go files are removed from the package and we execute gazelle, go_* rules are not removed from the BUILD file.

Example:

load("//:my.bzl", "my_go_binary", "my_go_library")

# gazelle:go_naming_convention import

# gazelle:map_kind go_binary my_go_binary //:my.bzl
# gazelle:map_kind go_library my_go_library //:my.bzl

my_go_library(
    name = "foo_lib"",
    srcs = ["main.go"],
    importpath = "example.com/foo",
    visibility = ["//visibility:private"],
)

my_go_binary(
    name = "foo",
    embed = [":foo_lib"],
    visibility = ["//visibility:public"],
)

What did you expect to see?

# gazelle:go_naming_convention import

# gazelle:map_kind go_binary my_go_binary //:my.bzl
# gazelle:map_kind go_library my_go_library //:my.bzl

What did you see instead?

load("//:my.bzl", "my_go_binary", "my_go_library")

# gazelle:go_naming_convention import

# gazelle:map_kind go_binary my_go_binary //:my.bzl
# gazelle:map_kind go_library my_go_library //:my.bzl

my_go_library(
    name = "foo_lib"",
    srcs = ["main.go"],
    importpath = "example.com/foo",
    visibility = ["//visibility:private"],
)

my_go_binary(
    name = "foo",
    embed = [":foo_lib"],
    visibility = ["//visibility:public"],
)
