Change should_replaced default value from false to true

@popy2k14 Why did you decide to include this change? In general, we do not like to modify a migration file once it has been created and then modify it later.

@agileware-oss i found it rather annoying that if you change the issue template to another one, the template of the new one get's added at the bottom of the current descritpion. In our case we have some tamplets like github, which are over a screen long.
Hence, the user changes the template and does'nt see that the new tenplate is added at the bottom.
With the function "should_replace" a nice popup will come up and asks the user to replace the content, so the user can decide.

I know it's an db migration script which alters the default setting of the "should_replace" behaviour.
But changing this will not change old installations (they are already migrated) but just new ones.

So new users will benefit from the should_replace feature by default and can deactivate it per project.
