info search and schema_info do not use the AsdfFile.extension_manager

[braingram]

Description of the problem

info (and search and schema_info) do not use the extension manager of the AsdfFile instance from which they're called. This can lead to a number of issues including:

• ignoring extensions passed to AsdfFile.__init__ (seen below)
• ignoring the standard version of AsdfFile (can be seen with small modifications to the below example)

Example of the problem

import asdf

MY_TAG_URI = "asdf://somewhere.org/tags/foo-1.0.0"
MY_SCHEMA_URI = "asdf://somewhere.org/tags/foo-1.0.0"

schema_bytes = f"""%YAML 1.1
---
$schema: "http://stsci.edu/schemas/yaml-schema/draft-01"
id: {MY_SCHEMA_URI}
title: "some title"
""".encode("ascii")


class MyExtension:
    extension_uri = "asdf://somewhere.org/extensions/foo-1.0.0"
    tags = [asdf.extension.TagDefinition(
        MY_TAG_URI,
        schema_uris=[MY_SCHEMA_URI],
    )]


asdf.get_config().add_resource_mapping({MY_SCHEMA_URI: schema_bytes})


class Thing:
    _tag = MY_TAG_URI

    def __asdf_traverse__(self):
        return []


ext = MyExtension()

print("=== Extension not registered ===")
# if we don't register the extension
af = asdf.AsdfFile({"t": Thing()})
# we don't see the title
af.info()

print("=== Extension registered with config ===")
with asdf.config_context() as cfg:
    # if we register the extension with config
    cfg.add_extension(ext)
    af = asdf.AsdfFile({"t": Thing()})
    # we see the title
    af.info()

# if we pass the extension to __init__...
print("=== Extension passed to __init__ ===")
af = asdf.AsdfFile({"t": Thing()}, extensions=[ext])
# we don't see the title
af.info()

Output:

=== Extension not registered ===
root (AsdfObject)
└─t (Thing): <__main__.Thing object at 0x103535030>
=== Extension registered with config ===
root (AsdfObject)
└─t (Thing): <__main__.Thing object at 0x10486a440> # some title
=== Extension passed to __init__ ===
root (AsdfObject)
└─t (Thing): <__main__.Thing object at 0x104b9d8d0>
