Ensure correct json default value normalization

`PostgreSQLSchemaManager::_getPortableTableColumnDefinition()` is
modified to call the private method `parseDefaultExpression()` on
default values for `JSON` field to correctly normalize doubled
single-quotes in json string value.

A test to cover this case is added.

Fixes doctrine#6357
