Legacy Data Issue: adding all contributor_alias.canonical_email that are not in contributor_alias.alias_email

Now, collectoss adds all emails from the facade task to the contributor_alias.alias_email column. For databases that existed before collectoss there needs to be row added for all contributor_alias .canonical_email that are not in the contributor_alias.alias_email

Potential query:
```
INSERT INTO augur_data.contributors_aliases (
alias_email,
canonical_email,
cntrb_active,
cntrb_last_modified,
tool_source,
tool_version,
data_source,
data_collection_date,
cntrb_id
)
SELECT
ca.canonical_email AS alias_email,
ca.canonical_email AS canonical_email,
ca.cntrb_active,
NOW() AS cntrb_last_modified,
'Manual' AS tool_source,
'0.0.1' AS tool_version,
'Manual Entry' AS data_source,
NOW() AS data_collection_date,
ca.cntrb_id
FROM augur_data.contributors_aliases ca
WHERE NOT EXISTS (
SELECT 1
FROM augur_data.contributors_aliases ca2
WHERE ca2.alias_email = ca.canonical_email
)
AND ca.alias_email LIKE '%@%';
```

Sub/related issue: #268

Note: this is different from #270 as that one is for contributors.canonical_email and this one is for contributor_alias.canonical_email

If email is added manually it may need to get removed from the unresolved table"

```
DELETE FROM augur_data.unresolved_commit_emails
WHERE email IN (
SELECT alias_email
FROM augur_data.contributors_aliases
);
```
