Fix the case-sensitive comparison on the seed name

[stephanetrou]

resolves #429

Description

To reproduce the Bug create a seed file named MySeed.csv in your seed folder with the following content :

adapter,version
glue,1.8.1

Run 2 times : dbt seed

The first time the table did not exist in glue metastore, so the command pass.

❯ dbt seed
14:37:32  Running with dbt=1.8.6
14:37:33  Registered adapter: glue=1.8.1
14:37:33  Found 1 seed, 879 macros

The second time the command did not pass

I find in the Athena documentation (sorry not in Glue documentation) Database, table, and column name requirements

Acceptable characters for database names, table names, and column names in AWS Glue must be a UTF-8 string and should be in lower case.

To solve this issue I added lower function in the where statement ("tableName == lower('MySeed')").
