Allow purging sqlite db with out dropping the existing db

[phillipsb22]

Problem I am using a custom build sqlite database that causes issues when I drop and try rebuild here liip/test-fixtures-bundle/src/Services/DatabaseTools/ORMSqliteDatabaseTool.php:63

Suggested solution I would like to implement an additional parameter that gets passed through to the load fixtures function that will allow the database to not be dropped but rather purged liip/test-fixtures-bundle/src/Services/DatabaseTools/ORMSqliteDatabaseTool.php:72

Additional info I would like to know if this is a feature you would like added or do you see problems with adding a feature like this? I don't see this as a breaking change to existing code, let me know if you would be happy with me implementing this and sending a PR. If so can you please state what you would need to merge it in
