[5.2.33] increment() on a relationship generates invalid SQL for Postgres

[pmatseykanets]

After upgrading from 5.2.31 to 5.2.33 noticed that increment() method called on a relationship i.e.

$exchange->tags()->increment('ref_count');

generates an invalid SQL (at least) for Postgres and breaks the app with an error:

Illuminate\Database\QueryException: SQLSTATE[42703]: Undefined column: 7 ERROR:  column "tags" of relation "tags" does not exist
LINE 1: update "tags" set "ref_count" = "ref_count" + 1, "tags"."upd...

5.2.31 produces the following SQL

update "tags" set "ref_count" = "ref_count" + 1, "updated_at" = ?
  from "exchange_tag" 
 where "exchange_tag"."exchange_id" = ? 
   and "tags"."id" = "exchange_tag"."tag_id"

whereas 5.2.33

update "tags" set "ref_count" = "ref_count" + 1, "tags"."updated_at" = ? 
  from "exchange_tag" 
 where "exchange_tag"."exchange_id" = ? 
   and "tags"."id" = "exchange_tag"."tag_id"

See how table name "tags" crawled in for updated_at?

What about in 5.2.32 please?

5.2.32 is OK. The whole test suite is green. So it looks like this bug was introduced in 5.2.33.

Ping @taylorotwell.

Can you try on latest tag: 5.2.34?

Seems to be working fine in 5.2.34. The test suite is green. Thanks.
