LP1910288 Bootstrap opac: E-items lines always display in account summary.
The E-item summary of ckos and holds always display in the My Account Summary of the Bootstrap Opac
regardless of the ebook_api.enabled flag in config.tt2. This fixes that issue.
It also sets both the ebook_api.enabled and ebok_api.ebook_test.enabled flags to default to false.
To test:
1. Set ebook_api.enabled in config.tt2 to false.
2. Look at a patron's account summary and notice that it displays the e-item lines.
3. Apply the patch.
4. The E-item lines are now suppressed.
