Add missing Locale.ENGLISH

[Fudeveloper]

it will cause some hard-to-find problems.

bug reproduction:

Locale trLocale= Locale.forLanguageTag("tr-TR");
String columnName = "i_test";
String columnPrefix = "I_";

System.out.println(columnName.toUpperCase(Locale.ENGLISH));
System.out.println(columnName.toUpperCase(trLocale));
System.out.println(columnName.toUpperCase(Locale.ENGLISH).startsWith(columnPrefix.toUpperCase(Locale.ENGLISH)));
System.out.println(columnName.toUpperCase(trLocale).startsWith(columnPrefix.toUpperCase(trLocale)));

result:

I_TEST
İ_TEST
true
false

As shown in the figure, the 'String#toUpperCase' method has been used 23 times.

21 times with the parameter of i18n(Locale.ENGLISH).

The special two times are added in this commit.
