Do not fail if "spring.datasource.url" cannot be resolved

Previously, a condition checked the value of "spring.datasource.url" to
determine if an embedded database has to be created as a fallback. When
the value is set with an unresolved placeholder, this fails even if
the DataSource is going to created by another mean ultimately.

This commit makes a more conservative check by only checking the
presence of the property rather than its value.

Closes gh-20438
