JSON Parsing failure results in NPE

[BarDweller]

malformed mappings.json entries such as

  "cloudant": {
    "credentials": {
      "searchPatterns": [
        "user-provided:cloudant-test:username",
        "cloudfoundry:cloudant",
        "env:cloudant_credentials",
        "file:/server/localdev-config.json:cloudant_credentials"
      ]
    }
  }

Cause project start up to fail with an NPE

Caused by: java.lang.NullPointerException
    at com.ibm.cloud.spring.env.CloudServicesConfigMap.getValue (CloudServicesConfigMap.java:128)
    at com.ibm.cloud.spring.env.CloudServicesPropertySource.getProperty (CloudServicesPropertySource.java:39)
    at org.springframework.boot.context.properties.source.SpringConfigurationPropertySource.find (SpringConfigurationPropertySource.java:111)

Seemingly because the code makes an assumption that there will always be an immediate child of a mappings.json entry called searchPatterns and does not test for the situation where that does not exist.

in this case the malformed json has 'credentials' as the child, which means this code
https://github.com/ibm-developer/ibm-cloud-spring-bind/blob/master/src/main/java/com/ibm/cloud/spring/env/CloudServicesConfigMap.java#L127-#L128
fails because 'array' ends up as null causing the NPE.
