Migrations dropping all indexes

[remcoabc]

Package versions and database engine type (please complete the following information):

• Database Engine: [mysql]
• TypeORM Version: [e.g. 0.2.41]
• Driver Version [e.g. 2.3.4]

Describe the bug
When we generate a migration without any changes to the entities it will generate a migration in which all indexes are dropped and created again.

What result we expect
We expect a message which states that there are no changes

@ArsenyYankovsky Do you know if this is a known issue?

@robbertstevens @ArsenyYankovsky I am seeing the same issue was wondering if this is a typeorm issue or a driver issue?

[robbertstevens]

No, idea. I have no experience with Typeorm besides this.

I'm seeing the same issue with this driver.
If I run a local mysql 5.7 docker container then use the mysql driver and run the migration generation pointing to this then the migrations are generated correctly.
We're on typeorm 0.2.38 and typeorm-aurora-data-api-driver 2.3.4 but I did some testing with the latest versions and this issue still exists.
If I get a bit more time I'll do some more testing and see if I can pinpoint where this is happening but probably going to have to use the docker setup as a workaround for the moment.
