Bug 13794: Text input field values not translated

I left the code logic intact, and simply removed "text" from the regex.
Text input field values are now translated, no other logical changes are introduced.

Test:
1) Update, install and enable es-ES language
2) Go to Reports > Acquisition wizard
3) On page bottom, there is a text field with the word 'Export'
4) Switch language, the word is not translated
5) Apply the patch
6) Update and install again es-ES language
7) Reload page, text now reads 'Exportar'

No koha-qa errors.
