Fix migration conflict

After enforcing this on application level in commit 4c37351, we can now also add
a unique constraint on DB level and a migration to fix any left over non-unique entries.

+    Historically, pretix recorded tax rates as decimals with two places. Today, pretix supports tax rates with up to

+    "19.00" to "19.0000" without warning. While this is semantically the same thing, we need to assume some pretix API
+    users might run into trouble, either because they treat the value as a string and then map something
+    (e.g. ``if tax_rate == "19.00"``) or process it with a language where this is a significant difference. For example,
+    while in Python ``Decimal("19.00") == Decimal("19.0000")`` is true, in Java
