Hardcoded migration map table name causes errors

Problem/Motivation

The table name is hardcoded in the query, which is causing this error:

In ExceptionHandler.php line 56:

SQLSTATE[42S02]: Base table or view not found: 1146 Table 'acquia.migrate_map_d7_views_migration' doesn't exist: SELECT "mmvm"."destid1" AS "destid1", "mmvm"."sourceid1" AS "sourceid1"
FROM
"migrate_map_d7_views_migration" "mmvm"
WHERE "sourceid1" IN (:db_condition_placeholder_0); Array
(
[:db_condition_placeholder_0] => archive
)

Proposed resolution

Fetch the table name dynamically and use it.
