Change setter name for isolationLevelForCreate in AbstractJobRepositoryFactoryBean

[fmbenhassine]

AbstractJobRepositoryFactoryBean provides two overloaded setters for the isolationLevelForCreate property: one that takes a String as a parameter, and one that takes an enum org.springframework.transaction.annotation.Isolation. This can cause ambiguity when Spring tries to set the property in XML configuration when selecting the setter to use, and can lead to:

Caused by: org.springframework.beans.ConversionNotSupportedException: Failed to convert property value of type 'java.lang.String' to required type 'org.springframework.transaction.annotation.Isolation' for property 'isolationLevelForCreate'; Cannot convert value of type 'java.lang.String' to required type 'org.springframework.transaction.annotation.Isolation' for property 'isolationLevelForCreate': no matching editors or conversion strategy found

The Spring recommendation for this is to use different names for setters. This issue is to rename the setter that takes the Isolation enum as a parameter to setIsolationLevelForCreateEnum.
