Handle default database for persistent connection

[abarkine]

This change is a fix for change #462 . Specifying both default database (as 0) and persistent (as true) results in falsy persistent setting. In mentioned PR, there is a mentioned predis change, which works only if persistent key is not boolean.

Since we are interested in persistent => true cases, it is required to check if mentioned database is falsy or not.

@B-Galati i run git remote add upstream https://github.com/snc/SncRedisBundle and git rebase upstream/master. Which step was wrong, how can I solve it? Should I create new PR?

[B-Galati]

No need for another MR.

Do git rebase -i upstream/master and remove lines that do not belong to your MR.

[abarkine]

Should be good now hopefully.

[B-Galati]

No it's not, it should have one commit only.

did you git fetch before? Make sure to have the option -i on rebase.

[abarkine]

Now?

[B-Galati]

Perfect, thanks @asilelik.
