fix: Fixing NPE bug by adding to if clause

[nick-redfearn]

Bug fix for NPE

NPE is...

java.lang.NullPointerException: Cannot invoke "java.lang.CharSequence.length()" because "this.text" is null

From my stacktrace...

java.lang.NullPointerException: Cannot invoke "java.lang.CharSequence.length()" because "this.text" is null
	at java.base/java.util.regex.Matcher.getTextLength(Matcher.java:1808)
	at java.base/java.util.regex.Matcher.reset(Matcher.java:461)
	at java.base/java.util.regex.Matcher.(Matcher.java:256)
	at java.base/java.util.regex.Pattern.matcher(Pattern.java:1180)
	at com.google.cloud.bigquery.BigQueryImpl.create(BigQueryImpl.java:436)
	at com.google.cloud.bigquery.BigQueryImpl.create(BigQueryImpl.java:363)

Looks like a bad null check to me

Thanks for contributing.
Can you run:
mvn com.coveo:fmt-maven-plugin:format
to fix the lint error (line too long).
Otherwise, approved. Just need to run few integration tests prior to merging.
