Fix EZP-23911: ezwordtoimageoperator with $size[0] not set

[Adcaelo]

using php "reset" function to retrieve first element of $sizes array because $sizes[0] is not always set

ex. in ezpublish_legacy/share/icons/crystal-admin/icon.ini

[IconSettings]
# Defined sizes, each size refers to the name of the subdirectory
# of the icon theme. If the name contains two numbers with an
# x in between it will be considered to be the width and height
# of the icon, if not no size is will be given
Sizes[]
Sizes[normal]=32x32
Sizes[small]=16x16_indexed
Sizes[ghost]=16x16_ghost
Sizes[original]=16x16_original
