Unable to migrate EasyListChina subscription

Environment

• Extension using this toolkit:
  • test-mv2 (based on 0.6.1)
  • test-mv3 (based on 0.7.0)
• Commit hash: 0.7.0

Steps to reproduce

1. Set value of "version" property in manifest.json file to "0.0.2" to avoid #383 (closed).

3. Install "test" directory as unpacked extension.
4. Run await EWE.subscriptions.add("https://easylist-downloads.adblockplus.org/easylist.txt").
5. Run await EWE.subscriptions.add("https://easylist-downloads.adblockplus.org/easylistchina+easylist.txt").
6. Remove "test" directory.
7. Copy "test-mv3" directory and rename it to "test".
8. Reload unpacked extension.
9. Run await EWE.subscriptions.getDownloadable().
10. Run EWE.subscriptions.getMigrationErrors().

Actual behavior

• EasyList was migrated.
• EasyListChina was not migrated.
• Migration error: "Failed to find the subscription with URL=https://easylist-downloads.adblockplus.org/easylistchina+easylist.txt"

Expected behavior

• EasyList was migrated.

Further information

It seems that EasyListChina's URL changed from https://easylist-downloads.adblockplus.org/easylistchina+easylist.txt to https://easylist-downloads.adblockplus.org/easylistchina+easylistchina_compliance+easylist.txt between the releases of EWE 0.6.1 and 0.7.0.
