PR move `get_basic_names(tags, geometry)` function from `transportation_name_tags` function and adding it after `transportation_name_tags` resolve street abbrevation.
PR runs through `test-sql` test without error. Adding to `osm_transportation_name_network` (table and for update) was done in consequence of `test-sql` errors ([update test 500](a747d98550/tests/test-post-update.sql (L53))). Originally `get_basic_names` was just in `osm_transportation_name_linestring` table.

Remove `STRICT` statement from `transportation_name_tags` function.
Concurrently with remove `STRICT` from `get_basic_names` and `get_latin_name` in OMT-T
FIX#1319
I discovered this bug while investigating issues with the updates process related to #1190#1292, and #814.
The `transportation_name` layer produces slightly different `tags` hstore values in the `osm_transportation_name_linestring` table during the initial import versus when running an update. As currently written, the import code produces null-value keys in the `tags` column, while the update code suppresses them. This PR removes that difference and makes the import code use same method that is currently used in the update code.
With a test case I've written, the import code produces a tags hstore that looks like this:
`"name"=>"OpenMapTiles Secondary 2", "name:de"=>NULL, "name:en"=>NULL, "name_int"=>"OpenMapTiles Secondary 2", "name:latin"=>"OpenMapTiles Secondary 2"`
...while the update code produces a tags hstore that looks like this:
`"name"=>"OpenMapTiles Secondary 2", "name_int"=>"OpenMapTiles Secondary 2", "name:latin"=>"OpenMapTiles Secondary 2"`
Note the missing NULL values.
This bug causes a small amount of space wastage after an update is run, because the update matching code detects the `tags` value as different, resulting in a duplicate copy of the tags value if that row is updated. This causes duplicate objects and breaks GROUP BY clauses that expect to group same-tagged features together. I've tested this by inspection of a generated mbtiles, database spot checks, and the unit test code included in this PR.
