Change how the replacements take place when anonymizing the support bundle.

It seems like the process doesn't replace by words.

Acceptance criteria:

Job with name some in the instance. The ContentMapping for the anonymization becomes some -> randomname. Then:

• Text in log: It's an awesome message thrown in some place of the code
• Currently: It's an awe*randomname*some message thrown in randomname place of the code
• Desired: It's an awesome message thrown in randomname place of the code

It could help to make the bundle more readable without losing protection of sensitive information.
