Fix "Upgrade 'dbName' blocked by other connection" warning when changing table schema

[NateLevin1]

Whenever you set a table's schema then change it the following warning is thrown.

Upgrade 'dbName' blocked by other connection holding version n

The rest of the behavior is perfectly normal AFAIK but the warning is always thrown.

Code Example
First, have a table constructor like this

const tbl = new Table(`CREATE TABLE tbl (
  id AUTO_INCREMENT,
  firstName,
  lastName
)`, db);

then edit it to

const tbl = new Table(`CREATE TABLE tbl (
  id AUTO_INCREMENT,
  firstName,
  lastName,
  email
)`, db);

and when running again the warning will be thrown.
