Samuel Tan db042d2d42 html/template: handle nil Error values in context.String
Add a special case to print a generic nil error when context.err is
nil.

Previously, this case was unchecked, leading to a call to (*Error).Error
with a nil receiver, which was triggering a nil pointer access. However,
this bug was masked by the panic-recovery code in package fmt.

I tested this change by running `dlv test` in src/html/template, running
the `continue` command, and verifying that no "bad access" errors are
returned.

Fixes #28854
